The JSON is not valid. (Parameter 'JSONPayload') Error Orchestrator HTTP Request

[gururaser (Gurur Aşer)]

Hi everyone,
I am trying to start a job with input parameters using Orchestrator HTTP Request activity:

When I pass this code to JSON Payload section

"{startInfo: {ReleaseKey: '-----',Strategy: 'ModernJobsCount',JobPriority: 'Normal',InputArguments: '{strCompany:'---',strURL:'" + strURL +"'}',JobsCount: 1}}"

I get error in Orchestrator:

The JSON is not valid. (Parameter ‘JSONPayload’)

System.ArgumentException: The JSON is not valid. (Parameter ‘JSONPayload’) —> Newtonsoft.Json.JsonReaderException: After parsing a value an unexpected character was encountered: T.

But I exactly do the same with videos below:
UiPath Tutorial | Orchestrator HTTP Request - Start Job using Release Key and Robot ID (youtube.com)
UiPath Orchestrator API Using Orchestrator HTTP Request Activity | Part 6 | Run the Job from Studio (youtube.com)

Can you help me ?

Have you cross-checked within Swagger as a side check?

[gururaser (Gurur Aşer)]

I don’t have so much information about Swagger, can you explain to me what do you mean ?

[ppr (Peter Preuss)]

with swagger we can learn and prototype ORC Rest Calls

Authorize at first

then prototype the call

[gururaser (Gurur Aşer)]

Hello, I checked even If I don’t understand Swagger much, but I can start job with Postman.
I can’t start a job inside of automation using HTTP Orchestrator Request activity

@gururaser

but I can start job with Postman

thats good, because we can port the settings / done item from Postman to HTTP Orchestrator Request. In general it is about the URL and the body payload

[gururaser (Gurur Aşer)]

The problem starts with Json Payload, I can’t use the json payload in the activity which I use in postman. If you look at the videos I provided with links you will understand

I exactly do the same thing with videos but I can’t understand I can’t reach to my goal

@gururaser

I can’t use the json payload in the activity which I use in postman

we do have several options to prepare the Json

Assign / Payload field - Singleline with escaped inner " like:
“{”“ABC”“: {”“CDE”“: 123},”“EFG”“:”+Var1+“}”

OR
Reading a text template with placeholders and replace the placeholders with

• String Replace
• String.Format Method and options

Just to mention a few options.

[gururaser (Gurur Aşer)]

Unfortunately, I’ve already tried these and they always give some syntax errors.

Also I checked my writing style from this website:
JSON Online Validator and Formatter - JSON Lint

[ppr (Peter Preuss)]

please share your XAML, so we can inspect. Also share with us a screenshot from the reference Packages, as we can check for the same settings. Thanks

[gururaser (Gurur Aşer)]

I tried more about your last response and finally I made it work!!!

Thank you!!

I would like to close but now I am facing issue while adding double value json string
Is there way to assign double value directly or do I have to transform it into string ?

I got this error:
Orchestrator HTTP Request: Expression Activity type ‘VisualBasicValue`1’ requires compilation in order to run. Please ensure that the workflow has been compiled.

with this JSON
"{""startInfo"":{""ReleaseKey"":""--------"",""Strategy"":""ModernJobsCount"",""JobPriority"":""High"",""InputArguments"":""{\""strCompany\"":\""------\"",\""strURL\"":\""" & strURL & "\"",\""strSize\"":\""" & strSize & "\"",\""doublePrice\"":" & doublePrice & ",\""createdOrderUID\"":\""" & createdOrderUID & "\""}"",""JobsCount"":1}}”
